The E! News chat Brandy conducted with Monica and Houston's friend and mentor Clive Davis has become a talking point since the tragedy, because Houston interrupted the interview and appeared to shock her young friend with the contents of a note that she handed to her.

In the footage, Brandy suddenly fell silent and shifted awkwardly in her chair after her brother Ray J's reported girlfriend handed her the note, which she handed off to an assistant

But in a new E! News segment, which aired on Tuesday, the singer insists she'll never reveal what her friend and idol wrote.

She says, "I'm going to just not say what it was and just keep it to myself for my own personal reasons."

Still raw and emotional after Saturday's tragedy, Brandy fought back tears for the new interview with Monica, stating, "It's just so unfortunate. Whitney meant everything to me -- everything. She's the reason that I sing. It's crazy, so crazy."
